javiers insurance company pays for 70% of the cost of an ambulance ride, after he pays a $150 deductible. the ambulance ride costs $1300. how much would javier pay for an ambulance ride? $540 $495 $390 $345
Answer
Answer:
B. $495
Explanation:
Step1: Calculate cost after deductible
$1300 - 150=1150$
Step2: Find Javier's share of remaining cost
Javier pays $100%-70% = 30%$ of remaining cost. So $0.3\times1150 = 345$
Step3: Calculate total Javier pays
Add deductible to his share of remaining cost. $150+345 = 495$
